To examine the association of metabolic syndrome (MetSyn) with occupational physical activity (OCPA) and leisure-time physical activity (LTPA) among working women.
The prevalence of MetSyn was calculated for 642 working women. Self-report questionnaire was used to determine levels of OCPA and LTPA and other lifestyle factors. Biometric data were directly collected on all women.
No direct relationship for OCPA and the MetSyn was determined. Sufficient LTPA however, was significantly associated with lower prevalence of MetSyn. No dose response relationship was determined with PA and MetSyn. The odds of having MetSyn was significantly higher for sedentary workers with insufficient LTPA compared with those achieving sufficient LTPA. The odds for MetSyn were similar among women employed in moderately active or heavy work yet completing insufficient LTPA compared with women doing sufficient LTPA.
For women with sedentary occupations, a sufficient amount of LTPA is essential to reduce the risk of having the MetSyn. Women in moderate to heavy working occupations may be acquiring adequate amounts of PA to avoid having the MetSyn.
